Shouldn't you mention it will look for device type on CONSOLE_DEV_TYPES if device_type is None and machine is not None?

How about this: ... @param device_type: the device type, such as "isa-serial". If None is given (the default value) a "-serial chardev:console" command line argument will be used instead, resorting to the machine's default device type, if a machine type is set, and a matching entry exists on CONSOLE_DEV_TYPES. ... > The description on set_console()'s docstring is out-of-sync with current > implementation too. > Good catch! I'm rewriting that as: ... This is a convenience method that will either use the provided device type, of if not given, it will use the device type set on CONSOLE_DEV_TYPES if a machine type is set, and a matching entry exists on CONSOLE_DEV_TYPES. ...

The set_console() utility function traditionally adds a device either based on the explicitly given device type, or based on the machine type, a known good type of device. But, for a number of machine types, it may be impossible or inconvenient to add the devices my means of "-device" command line options, and then it may better to just use the "-serial" option and let QEMU itself, based on the machine type, set the device accordingly. To achieve that, the behavior of set_console() now flags the intention to add a console device on launch(), and if no explicit device type is given, and there's no definition on CONSOLE_DEV_TYPES, the "-serial" is going to be added to the QEMU command line, instead of raising exceptions.
